| − | Methanol consists of a single carbon atom, with three hydrogen atoms and a -OH. Traditionally, methanol was produced by the fermentation of wood, leading to the term 'wood alcohol'. Industrially, methanol can be produced by the reaction of [[carbon monoxide]] and [[hydrogen]] (CO + 2 H<sub>2</sub> = CHO<sub>3</sub>OH). The primary use of methanol is its addition to ethanol to make it undrinkable. | + | Methanol consists of a single carbon atom, with three hydrogen atoms and a -OH.

Industrially, methanol can be produced by the reaction of [[carbon monoxide]] and [[hydrogen]] (CO + 2 H<sub>2</sub> = CHO<sub>3</sub>OH). For this industrial process, copper, zinc oxide and aluminum oxide may be used as catalysts at 250°C and a pressure of 50-100 atm. |
| | + | Methanol is highly toxic to humans. This toxicity is largely indirect, as alcohol dehydrogense metabolises methanol to form [[formaldehyde]], which causes blindness and death. Small amounts of methanol may be present in alcohol drinks are can cause a burning sensation of the eyes. |
